I think an excellent option for you would be the new Harman/Kardon AVR240. You can get it at
OneCall for $399.
This unit supports all major audio codecs (DD, DPLIIx, DTS) and also has the Pre-Amp outputs you are looking for (RCA output). Also a modest 50 watts x 7 channels, so you'd have a fully functional 7.1 receiver.
The Benefit of running all your Audio and Video to the receiver is having a single source. This way, you switch inputs on JUST the receiver when switching sources, not switching inputs on your receiver for audio, then on your TV for video.
UNFORTUNATLY, unless the receiver you purchase 'scales' non-HD signals (S-Video, RCA) to HD (480p), you WILL have to change inputs on the TV even though you may be running everything through the receiver.
My suggestion is getting a remote you can setup macros through. I use the Harmony line of remotes from Logitech, and honestly, I think it kept my wife from leaving me
Instead of having five different remotes, you now have one remote with simple buttons. For example, on my system the button "Watch TV" does the following:
- Turns everything on
- Sets the receiver to Video 1
- Sets the switch box to Cable
- Sets the TV to Component Input
This way, my wife didnt need to try and manage five remotes.
Hope I didn't overload you with information!
Cheers!
